Ruben Fidalgo

Ruben Fidalgo was the captain of the Portuguese Navy frigate San Carlos. In 1719, San Carlos and four gunboats were sent to attack the pirate ship Jackdaw as it sailed towards Sao Tome and Principe, but the pirates incapacitated the frigate and boarded it. Fidalgo was forced to surrender after most of his crew members were killed, and the frigate was plundered and used to repair the Jackdaw before it was scuttled.
